Fabian Christ updated STANBOL-622:
----------------------------------
Component/s: Enhancer
Fix Version/s: enhancer-0.10.0-incubating
> The KeywordLinkingEngine should check if all Tokens of a Label match against
> the text

> Key: STANBOL-622
> URL: https://issues.apache.org/jira/browse/STANBOL-622
> Project: Stanbol
> Issue Type: Bug
> Components: Engine - KeywordExtraction, Enhancer
> Affects Versions: 0.9.0-incubating
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Fix For: enhancer-0.10.0-incubating
>
>
> Currently the KeywordLinkingEngine generates a lot of suggestions for phrases
> like "{noun/noun phrase} {preposition}".
> E.g. for the sentence
> "Mexico City is by far the biggest urban area of Mexico"
> the KeywordLinkingEngine would suggest
> "Urban areas of England"
> "Urban areas of Sweden"
> for
> "urban area of"
> However the intended behavior would be to
> (a) match "urban area of Mexico" if this concept exists in the controlled
> vocabulary ... currently not the case in DBpedia
> (b) match the text "urban area" with the concept "urban area" and possibly
> include "Urban areas of England" and "Urban areas of Sweden" as additional
> suggestions.
> The cause for the faulty behavior is that currently the KeywordLinkingEngine
> does only check if all Tokens of the selected Region of the Text match
> against the label, but does not check if all Tokens of the Label do also
> match the selected Region of the Text.
> Because of that "Urban areas of England" and "Urban areas of Sweden" or
> treated as FULL match for "urban area of" and therefore making this
> preferable to selecting "urban area" with the EXACT match "Urban Area".
